Ok so this is clearly not a real video but it is something all young women go through at some time in their life. Getting your first period is actually clearly something new and one of the many signs of growing up. It is not however all that great.
In the vid a mother finds her daughter has used red nail paint to pretend she has reached that stage in her development. The mom then plays a bit of a joke on the girl by throwing her a First Moon Party.
By the end of the clip, you realise what the mom is up to and it all leads to a pretty clever end.
That little girl is like a female version of Malcolm from “Malcolm in the Middle”.
